Management of Vertical Handoffs

A news release noting an installation of a cognitive system from In Motion Technology for East Texas Medical Center (ETMC) Regional Healthcare System Emergency Medical Services. Reading into their solution page and technology page, what they’re actually doing is optimizing the choice of network assignment based on link information and performing vertical handoffs. Think normal mobile assisted handoffs (maintain a ranked list of link state information from multiple base stations and switch when some hysteresis threshold is crossed), but not restricted to a single wireless interface.

It’s not what most people would call full-blown cognitive radio, but this is representative of how I think cognitive radio is going to roll out – function by function.

White Space Device Resubmission

Motorola is resubmitting their white space device to the FCC for testing. Not much information in there but it’s interesting to note.

US Navy Video on spectrum

Via Elastic Spectrum, comes this video entitled, “Electromagnetic Spectrum, Critical to our Nation’s Security and Economy.” Beyond the video (kind of an overview), there’s also several nice reference documents linked on the sidebar at the site
